Solved Intermittent failures on USB 3 ports on new mobo


#1
I've been struggling for two months to fix a situation where one or more USB 3 ports on my PC would fail, usually --but not always -- under heavy I/O loads. Read about the problem and my ultimate fix at Unraveling a USB Mystery | Ed Tittel. Sometimes, you just have to replace the wonky hardware with a known good working replacement. Sigh.
